FILMMENDING MACHINE.

Specification of Letters Patent.

Patented N0v.'12, 1912.

Application filed October 26, 1911. Serial No. 656,853i

To allwhom it may concern.

Be it known that I, EDWARD J. SCHAFER, residing at Seaside, in the county of Clatsop and State of Oregon, have invented a.

certain new and useful Improvement in Film-Mending Machines, of which the following is a specification.

My invention is a machine for use in mending or repairing moving picture films and the like. In the art of moving picture displaying, the pictures are contained on a long strip or film in successive arrangement. The film is perforated along its longitudinal edges with suitably spaced sprocket perforations that engage the sprocket wheels of the exhibiting machine, and are thereby'fed before the condenser lenses to enable the images to be projected with the light stream on to the screen and thus produce the view. It sometimes occurs that in winding or rewinding the films on the reels or when ru n.

ning films through projecting machines, etc., the film becomes torn or broken making it necessary to repair the same and rejoin the severed ends before the film can be used again. To do this requires that the film be scraped, and the torn edges trimmed down evenly so that a perfect joint and perfect registration of the perforations may be obtained. This operation is usually both long and tedious and usually requires the whole attention of the operator.

It is, therefore, one of the principal objects of my invention to provide a machine capable of "manipulation of one hand if desired, while the operators other hand is employed in turning the exhibiting or projecting machine; and by the use of which machine a perfect .mend may be easily and conveniently made without delay.

My invention primarily resides in providing a repairing machine that maybe attached to any rewinding machine, and in such a manner as to lie out of the way when not in use, and so that it may be swung out into the path of the film whenever it is desired to employ the machine.

The invention includes a transparent plate or table on which the film is laid in operating on the same and beneath which asource of illumination is located with a trans arent .s'heet of mica between thesource of illumination andthe glass table top to prevent heating and subsequent injury tov the film; clamps having dowels or pins to enter the.

perforations and hold the film section in position; tension devices for holding the adjacent ends of the films on the table;-a-

presser for holding the repaired parts down on the table until they have become firmly united; a gage for effecting the proper match of the two film sections; a cutting mechanism for trimming t-he torn ends of the film; meansfor insuring the proper relative position of the line of severance, and a scraper for removing the emulsion from the film body or base preparatory to making the repairs.

The invention also resides in those novel details of construction, combination and arrangement of parts, all of which will be.

hereinafter fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the invention inv use. Fig. 2 is a substantially central, vertical cross section of the ma-- chine, parts being shown in elevation. Fig. 3 is a horizontal section taken substantially on the line 3-3 of Fig. 2, the joined clamp being swung back. Fig. 4 is a detail section on the line 4 of Flg. 3. Figs. 5

and 6 are detail sections on the lines 5-5 6-6 respectively of Fig. 4. Fig. 7 is a de tail perspective view of the line gage, the cutter carrying bar and the'cutting mechanisms. Fig. 8 is a detail perspective view of the combined wrench and scraper. Figs. 9 and 10' are detail perspective views showing two methods of scraping the ends of films chine (not shown). 2 is the secondary base which carries the main frame or housing 3, and the bases 1 and-2 are'joined together by parallel levers 4 and by holding braces or links 5, so arranged and constructed that the bases may be held one upon the other when the machine. is not in use, and whereby they may be held in position when the housing is pulled forward to bring the table in alinement with thefilm.

The housing 3 has a removable froiit 6 which supportsa switch 7 of any approved type, the switch 7 controlling the lights 8 and 9 which illuminate the inside of the housing and the outside of the apparatus. The front 6 is held in place by suitable fastenings.

The top of the light house 3 is formed of a transparent plate of glass 10 lined with a sheet of mica 11 to prevent heatingof the glass top 10, which-top is hereinafter termed the table.

Securely mounted on the-housing 3 to lie next to the table 10 is a frame composed of two side bars 12l3, united'by a straightedge plate 14 that crosses the table 10 longitudinally near its back edge, a sheet of rub ber 15 being interposed between the straight edge 14 and the table top 10 to insure a tight film sprocket holes 22 and enter the recesses sprocket holes 22in the films 23 and enter the recesses 24 in the respective hinged clamp bars 25, there being one bar 25 hinged at 26 to each bar 17 and 18. The bars 25 are retained in their clamping positions (see Flg. 4) by resilient clips 27 or other suitable devices. The-clips 27 have finger engagements 28. The bar 13 is also a clamped bar but it has no lateral adjustment as has the bars 17 and 18. The bar 13 is also provided with teeth or dowels-21 to piercethe 29 in the pivoted clamp 30 which is pivoted and the gage 39 may be adjusted .along the at 31 to' a projection '32 and is clipped down .by a suitable clip 33.

, The-bars 2525 and 30 are each lined or faced on the underside with rubber or other similar yieldable substance to press on the film without injuring the same. i

Mounted over thetable top 10 between the clamps 1725 and '1330 is a U-frame 34, that is elevated above the table and supports below its arms 35 a pair of pressers 36, the same having guides 37 and being ad-' justable through tensions 38 as best indicated in Fig. 1. Mounted beneath the U- frame. 34 and over the straight edge 14 is a gage 39-.whose pointers 40 are spaced adefinite distance apart, say two film spaces,

table by a cam 41 that operates between'the abutments 42 on the gage 39 and is turned 'by a finger piece 43 (see Figs. 1 and 3).

The gage 39 carries a bar 44 which has a finger '45 to projectthrough bearings 65 on the clamp bar 18 andwhich carries a cutting mechanism which comprises a shear frame 46 formed of a pair of parallel plates s aced .upartisufiiciently to receive the kni e 47.

The knife 47 is pivoted on the finger on which the frame 46 is mounted. The frame 46 is adjustably secured to the bar 44 to move with it, by a set screw 48 and slotted projection 49. 50 is a guide rod projecting laterally from the bar 13 and on which the front of the shear frame 46 is guided, the rod lying in the recesses 51 of the frame 46.

The cutting mechanism 4647 lies between the clamps 13-30 1825.

52 is a block fastened to the bar 18 to serve as a support for the lap end of the film while it is being scraped clear of w ulsion preparatory to mending the same; the clamp bar 25 which is adjacent to the block 52 serves as a straight edge or guide for the scraper to prevent scraping over the (lividing line on the film, and in case the film is of such perforation as to project farther than flush with the straight edge of the side of the bar 25, the scraper is turned from the position shown in Fig. 9 to the position shown in Fig. 10, so that the notched corner will be adjacent to the bar 25.

53 is a joined clamp which is hinged at 54 to the housing and has a prcsser portion or foot 55 that is covered with rubber or the like 56, 'to press the repair'ed joint to the table top until the mend has become set. The joined clamp 53 has a port-ion 57 to be engaged and latched by the latch 58.

59 and 60 are the holders for the repairing cement containers 61 and 62.

.63 indicates the leading-in wires from a source of current supply that deliver the current through the switch to the respective lights.

Operation: When the device is not in use, the base 2 rests on the base 1 in its backward position (see Fig. 2-) so as to be out of way. When a film breaks the machine is pulled (see Fig. 1) to bring the table 10 in aline- -ment wlth the film,'the broken sections are clamped by the clamps 17-25 13--25, after which the gage 39 is adjusted to bring the cutting mechanism into proper position to sever the ragged end of the film sections. After the respective ends have been properlytrimmed, the emulsion is scraped off the contacting face of the lap cut end of the film by using any suitable scra er 64 for the purpose. The two sections 0 the film are then adjusted in the clamps and on the table to so that the lapping end will lie on the ta 1e 10 as indicated in Fig. 1. Proper alinement being attained by use of the straight edge 14 and the pointer 40, the film ends are held down by the ressers 36.

The cement is then applied to t e lapping surfaces to cause them to adhere. The oint clamp 53 is then fastened down (see Fi 2) to hold the joint firmly in place unti the cement has set, after which the film is removed from the machine repaired. By using the gage, a cut or trim at an exact 10- cation can be made to insure absolutealinement of the lapped ends and perfect registrybetween the sprocket holes thereof. By'

making the parts adjustable as indicated any style of film may be employed regardless of the relative location between the perforations, the cross lines and the ings it is thought the complete operation and advantages of my invention will be apparent to those skilled in the art, and I 'desire it understood that the form shown is a preferred one of which numerous modifications may be made by those skilled in the art without departing from the invention, v
